Challenge: availability and quality of water; Environmental changes are modifying how contaminants behave on the environment; Drugs adverse effects on biota and humans. How much are in human supply reservoirs? What are their ecotoxicological effects? How climate change can influence the behavior of drugs on the environment? Investigate the presence and ecotoxicological consequences of drugs in Brazilian aquatic ecosystems. INTRODUCTION GOAL MATERIAL AND METHODS EXPECTATIONS SOME DATA... Study Sites: environmental samples from reservoirs Experimentation: biogeochemistry and ecotoxicological effects: Chapéu D’Uvas (MG) Funil (RJ) Drought experiment Available on: Quadra et al. 2017 – Environmental Science and Pollution Research Sales of pharmaceuticals and population growth Pathways of pharmaceuticals in the environment New knowledge: concentrations, ecotoxicological effects, and behavior in the environment Elaboration of guidelines for control in the environment.
